The changing epidemiology of mechanical ventilation: a population-based study


The number of critical care beds in the United States has been increasing considerably, but it is unclear how these additional beds have been used. Mechanical ventilation for acute respiratory failure almost always demands ICU care and is likely to be a reliable indi-cator of critical care resource requirements on a population level. The objective of this study was to measure changes in the yearly incidence of mechanical ventilation in a statewide population. The North Carolina Hospital Discharge Database contains data on all discharges from nonfederal, nonpsychiatric hospitals in North Carolina. Authors extracted data on adult patients with International Classification of Diseases, 9th Revision, Clinical Modification procedure codes for mechanical ventilation from 1996 to 2002. The incidence of mechanical ventilation for adults grew from 284/100 000 population in 1996 to 314/100 000 in 2002, an increase of 11 % (P <.05). While patients aged>64 had the high
